Electric schooters - Electric Health & Beauty

Sounds like the coil is breaking down when it gets hot, try to get a replacement from a breaker.

Replace the screw and tighten securely

sould like the gears are dry and oil is low check the oil level. also look for leaks around the motors.

That is hard to determine because of the variables such as your weight, the age and charge level of the batteries, the terrain condition such as hills, the roadway surface and the pressure in the tires if they aren't solid. You should get around 15 miles or so under ideal conditions.

Hi, you really need to keep those batteries above 10c, minus 30 will freeze the contents, the battery will need to be thawed out before use* ( *Electric mobility advice). You will need to have a heated blanket that can safely be used outdoors otherwise you will always have problems with the batteries... Sorry but the cold kills batteries or battery power very quickly because they cannot transfer charge well.

Regards

more info needed, what make and model scooter?

I'm assuming you have a full charge on your batteries? The problem is that the charger can be fulled into thinking that your batteries are at a full charge when they are not. The battery will put out he correct voltage so your voltage gage reads right. The battery will put out the correct resistance so the charger will see a charged battery. Chargers work by resistance the lower the resistance the harder the charger works to charge the battery. So the only way to determine the real state of charge is to bring the batteries to a battery shop. Have them load test the battery in your presence if the battery is new. This is not a pass or fail test.What we are looking for is the upper limit of the cranking amps the battery will output.They may tell you this battery isn't supposed to be measured that way because in battery is not used to start a car. Well most of the equipment is geared for measuring car batteries. For what we are doing here it doesn't matter. For my scooter batteries i use two 12v 35amp/hr batteries. Have them grab a new one off the shelf, have them find the upper limit of the amp output. What happened to me is i didn't watch them do this test. The instrument he was using will give you a pass.or fail indication at a preset level of about 150 amp/hr unless you manually input a higher level to test for. This was a new battery and they want it to pass. I had them find the upper limit of a new off the shelf battery by entering higher values into the test instrument until it failed back off on the value until i found it passed. A new battery like the one my scooter uses will put out close to 500 cranking amps. Well when i tested my battery it barely reached 200 cranking amps. So in fact this battery doesn't have the capacity of the off the shelf battery. So as you load it the voltage goes down. My motor controller will detect that and give me a fail indication.

oK if this is not the problem we can look for amp leaks. Put a amp meter between the battery and the load. Turn the scooter off, get a reading?.If you do something is either on or a resistive short drawing down your battery. Disconnect stuff until the reading is zero. What ever you disconnected last will give you the section of the scooter the problem is coming from. Like if you disconnect the control head and it drops to zero i would start there. Turn the scooter on there should be an indication, but it should be under an amp. Now get the rear wheels up so that they can rotate freely. Apply just enough power to move the wheels. Look at the meter if its a analog meter does it jump around. Does the motor stall at any time. If the first thing happens you have a partially shorted winding in the motor. IF the second thing happens the meter will jump up or down indicating either an open or shorted winding.
Now floor it jot down the amp draw. IS it excessive? We check this by doing the math. My scooter use two 12 v 35 amp/hr batteries hooked in series. So i have a 24v system @ 35amp/hr, the scooter has a loaded range of 25 mile at a speed of 5 mph.So my battery life is going to be about 5 hours. So we can say the motor loaded on a flat surface will use about 7 amp/hr. So running the motor flat out unloaded is going to be less than 7 amp/hr. My scooter's motor runs at about >5 amp/hr unloaded. Hope this helps

Hi, try to sart the engine with your hand ( or someone eslse) covering the air intake of the carburator. If the engine gives you signs of firing, then you probably have a ail leak in you fuel sistem (betwen carburator and the engine) wich is giving you a wrong petrol/air mix.
